Abstract: A method for wirelessly accessing a vehicle including the steps of: exchanging data between a UID-transponder and the vehicle to verify authorization of the UID-transponder, triangulating a location of UID-transponder relative to the vehicle using at least three first antennas being positioned at three different first positions of the vehicle and providing access to the vehicle under the first authorization condition that the UID-transponder is identified as an authorized UID-transponder and if the location meets a second authorization condition as well, to recognize a relay attack.

Abstract: A method for remote controlling an object with a remote-control unit is provided. At least a first surface S1, S2, Si is defined in a first coordinate system. At least a first function of the object is associated to the first surface S1, S2, Si. A second coordinate system is defined at the position of the remote-control unit. A static pointing vector 28 is defined in the second coordinate system. It is then determined whether the pointing vector points towards the first surface S1, S2, Si. If so, the object is enabled to selectively activate the first operation upon receipt of an activation command.

Abstract: An authentication element that may include a keyless go device for a vehicle. The authentication element may include a transponding interface for transmitting an authentication signal and receiving power and data. A sensor element may also be provided for detecting a movement and/or inclination. The authentication element is designed such that authentication signals are transmitted over the transponding interface when the sensor element detects a stored movement and/or inclination. An authentication system for vehicles may include at least one authentication element and an apparatus.

Abstract: An apparatus for a vehicle key, an apparatus for a vehicle control system, and an apparatus for a mobile device. The apparatus includes a first interface to communicate with a vehicle control system and a second interface to communicate via a radio connection. The apparatus also includes a control module to receive proximity information from the vehicle control system via the first interface and to establish a radio connection via the second interface if the proximity information indicates spatial proximity of the vehicle key to the vehicle control system.

Abstract: An authentication element, specifically a keyless go device for a vehicle. The authentication element has a transponding interface for transmitting an authentication signal and receiving power and data. The authentication element also has a key button device for detecting user input, whereby the authentication element is designed such that authentication signals are transmitted over the transponding interface if the key button device detects user input. An authentication system for vehicles includes at least one authentication element and an apparatus.

Abstract: An arrangement on monitoring of authentication, in particular for motor vehicles, includes a first communication apparatus and at least a second communication apparatus, between which a wireless communication channel can be set up. The communication apparatus items have means for authentication and encryption, with which the exchangeable data may be encrypted via the communication channel. The items of communication apparatus have storage means in which one of the digital keys usable for authentication and encryption can be stored, and in that in the storage device there is either in addition to the digital key and/or in the individual key at least one piece of information regarding at least one past communication between the first communication apparatus and the second apparatus that can be stored in memory.

Abstract: In a method and a device (12) for actuating a door or flap (1) of a vehicle (10), the door or flap (1), if it is closed, is automatically opened or, if it is open, is automatically closed if a movement of an object with at least one change in direction is detected outside the vehicle (10) and at the same time a key (6) assigned to the vehicle (10) is detected.

Abstract: A key with remote radio operation, particularly for motor vehicles, includes a housing and electronic circuits arranged in the housing for the purpose of authentication of the key, wherein each circuit has an interface for communication with an authenticating entity outside of the key. The problem addressed is that of structuring a key for use with nascent transmission standards. This problem is addressed in that a first circuit of the key has a BTLE interface, and a second circuit of the key has an NFC interface, for the purpose of communication.
